How to use your bearer access token

Before you invoke an API call, you must be authenticated. When you have authenticated, you must mark each subsequent request with an HTTP header—Authorization with the Bearer access token set.

Your token expires after 1 hour. You can reuse your token as many times as you like during that time. To reuse your token, simply cache it and, each time you make a request, grab the token from your cache.

To avoid errors being returned by your API request due to an expired token, intercept 401 Unauthorized errors with a The access token is invalid or has expired message that your request receives when you use your cached token. If you receive such a message, request a new token and replace the cached value with the new one.
